The Wikipedia numbers should(!) be drawn from official sources, but that still doesn't make it very easy to compare across navies. Aside from Marines, which tend to be in a clearly identifiable subcategory, the greatest source of variance between different navies would be in shore support functions: what is handed within the service vs. what is handled by other departments or contracted out.
I think the 052s and 051B will go by 2030, maybe the first pair of Sovs too -- all will have been in service 30 years or more by 2030.
I expect PLAN will stick to the 30yr retirement curve now that production rates allow them to do so, if not move slightly ahead of it. The reasons for this are twofold: first, older PLAN ships are, relatively speaking, less capable than older ships of other navies, esp. Japan & US. Therefore, replacing an old vessel with a new one is going to provide an even larger increase in capability for PLAN than for other navies. Secondly, removing the older vessel from service allows PLAN to reassign the crew, thereby constraining growth in personnel and associated costs. If the raw capability of PLAN's older vessels is limited, the capability-per-crew is even worse: an 052 requires almost the same number of crew as an 052D.
The only reasons to retain destroyers >30 years old in service going forward that I can think of are:
1. If there is an imminent risk of war.
2. If future expansion plans will require more personnel than can usefully be accommodated without retaining those older ships in service.

LOL! Instant classic.
I merged a photo of 052d and the rare photo showing the radar opening on the port side mock up together, scaled for the 346A radar array in blue. I chose pictures which show the radar on about the same horizontal axis, although the 055 mock up photo was taken lower than the 052D. But for the purposes of this illustration I mostly only used the horizontal width of the array as a common metric. The assumption is the width of the arrays in both pictures are depicted accurately, I.e. The same angle.
The black lines are indicative of the superstructure for 055 and the red lines are for 052D. I think it gives a nice sense of scale regarding just how much bigger 055 will be compared to 052D when using a common metric. Specifically, it shows 055 will have a much greater beam, which we've known for some time.

Nice analysis, Blitzo, keep up the good work.
Similarly scaled side view (via PJ-38 gun) with 052D's array in blue. I think it demonstrates both 055 and 052D will have similar height of their main superstructure and have similar radar placement as well, but that 055's superstructure and overall beam is far greater.
Thanks bltizo. Based in this photo comparition,i have to say that i doubt that type 055 will have 12000t. This ship has aprox. 172+- meters of lenght (compared to 156 meters type 052d) and aprox 21+ meters beam (18 meters type 052d). Type 052d has 7500t. Will type 055 get to 12000t ? i have doubts.
Well, beam estimates have been anywhere from 21-23m.
It is worth considering that 055 will probably sit noticeably higher than 052D as well.
055 will also likely have a larger flight deck than 052D both in absolute size and as a proportion of their respective hull's lengths.
So there are many plausible ways for the ship to reach rumoured normal displacement of 12,000 tons.
I did a little contrast work to try and bring out the Type 052D a little better. I was having a hard time seeing it with my old eyes.
That's a little easire for me to see.

Do you know what the draft value for 055 will be? Otherwise, I don't know how you can rule out a 12k displacement.
Considering Burke FIIA's dimensions (155m x 20m x 9.3m) and displacement (9250 metric tons), with other factors being roughly comparable, it's perfectly within reason that 055 would displace close to 12,000 metric tons, assuming a length of 175m, beam of 21m, and draft of 9.8m (only 5% greater than that of Burke IIA).
Here's my back-of-the-envelope calculation:
[(175mx21mx9.8m)/(155mx20mx9.3m)]x9,250tons=11,555tons
Even a minute increase of the beam and/or draft value would send 055's displacement well north of 12,000 tons.
OR, if you prefer, let's compare 055 to 052D, and I'm gonna make the ludicrously conservative assumption that 055's draft value is EQUAL to Burke IIA's. The calculation is as follows:
[(175mx21mx9.3m)/(156mx18mx6.5m)]x7500tons=14,044tons
A whopping 14,044 tons!
Now, if we change the draft value to a more reasonable 9.8m, we get 14,799 tons. Just for kicks, plug in 21.5m for beam and 10m for draft, we get 15,460 tons.
That's 15,460 tons!
In fact, I'd be surprised if 055 doesn't end up displacing more than 12,000 tons if the rumored dimensions hold up.
Of course, my calculations are based on the assumption that 055 will exist in a three-dimensional space. If you believe the said assumption is unreasonable, please explain why this is so.
